In this project, funded by the Chemical Structure, Dynamic & Mechanism B Program of the Chemistry Division, Professor Todd A. Hopkins of the Department of Chemistry and Biochemistry at Butler University is developing unique solvents called deep eutectic solvents as circularly polarized light emitting materials. Deep eutectic solvents are well suited to the task, because of the ability to control their properties. This project explores how to design deep eutectic solvents that improve the efficiency of emitted circularly polarized light. Circularly polarized light emitting materials, such as circularly polarized organic light emitting diodes, have potential application in quantum computing, for generating holographic images, and as security labels. This project engages undergraduate students in research at the interface of physical, inorganic, and materials chemistry, and involves collaboration between undergraduate research students and students enrolled in a physical chemistry laboratory course. More technically, the goal of this project is to develop circularly polarized light emitting materials based on luminescent lanthanide complexes dissolved in deep eutectic solvents. Deep eutectic solvents are formed from combinations of hydrogen bond acceptor and donors, whose properties can be controlled through choice of components. Therefore, the selection of hydrogen bond acceptor with chiral hydrogen bond donor can generate a deep eutectic solvent that provides both chiral selection and charge carrier properties to enhance electroluminescence of the dissolved lanthanide complexes. This project involves 1) screening chiral hydrogen bond donors for low melting point deep eutectic solvent formation; 2) characterizing the physical properties of the deep eutectic solvents; 3) characterizing the chiroptical properties of lanthanide complexes in the successful deep eutectic solvents; and 4) developing circularly polarized organic light emitting diodes out of the successful deep eutectic solvent/lanthanide systems. The high-throughput approach to screening deep eutectic solvent properties in this project yields a large amount of data on deep eutectic solvent-structure property relationships that will be shared in a public database to help the research community develop better predictive models.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在该项目中，由化学结构，动态和机制B计划资助，Butler University化学和生物化学系的Todd A. Hopkins教授正在开发称为循环偏光光发光材料的独特溶剂。由于能够控制其性质，因此深层溶剂非常适合该任务。该项目探讨了如何设计深色溶剂，以提高发射圆形光的光的效率。圆形极化的发光材料（例如圆形极化的有机光二极管）在量子计算中具有潜在的应用，用于生成全息图像和安全标签。该项目吸引了本科生在物理，无机和材料化学的界面上进行研究，并涉及本科研究专业的学生与参加物理化学实验室课程的学生之间的合作。从技术上讲，该项目的目的是开发基于溶解在深色共晶溶剂中的发光灯笼复合物的圆形偏振光发射材料。深层溶剂是由氢键受体和供体的组合形成的，它们的性质可以通过选择组件来控制。因此，用手性氢键供体选择氢键受体可以产生深层溶剂，从而提供手性选择和荷兰载体性能，从而增强溶解的灯笼溶解的灯笼复合物的电致发光。该项目涉及1）筛选低熔点深共晶溶剂形成的手性氢键供体； 2）表征深色溶剂的物理特性； 3）表征成功的深共晶溶剂中灯笼植物复合物的手势特性； 4）从成功的深层溶剂/灯笼系统中，开发出圆两极化的有机光二极管。 The high-throughput approach to screening deep eutectic solvent properties in this project yields a large amount of data on deep eutectic solvent-structure property relationships that will be shared in a public database to help the research community develop better predictive models.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
